Tooth-brush.



FRED DOVVNING. ()F DECATUR, lLLINOlL I TOOTH-BRUSH.

Application filed October 19,

To all whom it may concern.-

Be it known that 1., F RED DOWNING, a citizen ofthe United States, residing at Decatur,

in the county of Macon and State of 'lliinois,

have invented new and useful Improvements in Tooth-Brushes, of which the following is a.

specification.

The invention relates to an nnprtweincnt 1n tooth-brushes, particularly of that class Specification of Letters Patent...

1905. Serial No. 283,488.

which the liquid may pass. The forward end of the valve-stein 10 is provided with a 1 valve 13, arranged when suitably positioned designed to carry a suitable supply of dcnti i frice.

is the production of a brush having a suitable dentifrice-cont aining compartment from which the material may be fed as desired, directly to the bristles of the brush, all of which parts are of the. particular specific construm tion hereinafter pointed out.

The invention in its preferred form of details will be described in the following spccification,.reference being had particularly to the accompanying drawings wherein- F igure- 1 is a view in elevation of my improved tooth-brush. Fig. 2 is a longitudinal section of the same. Fig. is a transverse section on the line 3 3 of Fig. transverse section on the line 4. 4 of Fig. 2.

Fig. 5 is a perspective detail of the valve and valve-rod.

Referring particularly to the drawings, wherein like numerals of reference designate like parts throughout the several views, iny

improved tooth-brush comprises a body portion 1, 'interiorly formed with a channel 2. By preference the channel 2 is divided as to present four channels arranged in dianietricr ally op 'osite pairs and converging at the forwart end into a single-channel The rear wall 4 of the body portion is formed with a central valve-opening 5 for a purpose hereinafter described. The rear end of the body portion isneduced and threaded to receive the forward threaded end of the dentifricecyglinderfi, which is of a size to contain a suit a le quantity of solution. The rear end of the cylinder 6 is threaded to receive a closin gcap 7', comprising a hollow body closed at its forward end to provide a conical head 8 and open at the opposite end and peripherally formed at said end with a flange 9.

10 represents a valve-ste1n longitudinally movable in the cylinder 6 being centrally guided in a partition 11, supported interiorly of the cylinder and cut away on opposite edges and to provide channels 12 through Fig. 4 is a to close the valvc-opening 5 in the rear wall of the body l. The coiled spring 14 terminally bearing against the forward face of the valve and against a fixed stop 15 within the channel 2 of the body operates to normally scat the valve 13 within and closing the valve opening At the rear end tne valve-rod is- 2 provided with avcylindrical button 16, slid- The main object of the present invention ably mounted in the closing-cap 7, being limited in its movement by the head 8 and flange 9 of said cap, as clearly shown in Fig.- 2. A stop 17 is provided on the valve-rod 10, designed to c uitact with the partition 11 and limit the l u rement of the valve-rodin the closing operation.

18 represents a brush-back comprising a suitably-sized strip reduced and threaded at its rear end to engage a threaded opening 19, formed in the forward wall of the body 1.- The brush-back is provided with suitable bristles 20, which may be arranged in any suitable form oroutline desired. 1

Afeed.'-tube 21 open at itsforward end,is in communication with the channels 2 in the body 1 by having threaded connection with an opening 22, formed in the forward wall of the body 1, which opening is in direct communication with the single channel 3, leading froni the channels 2.

In operation pressure upon the button 16 in the forward direction moves the valve 13 against the tension of the spring 14 and permitting the contents of the cylinder 6 to pass through the channels 2 and through the tube 21, being discharged from said tube through suitable openings 23 into contact with the bristles'of the brush.

-It will be noted that the button is piotected against accidental operation by being normally seated within the closing-cap without projecting portion, thatthe cylinder 6 may be readily filled with suitable dentifrice by removing the closing-cap and push-button 16, the valve-rod prevented from movement by contact with the stop 17 with the partition 11, that through the threaded connections described the parts are connected to prevent leakage and at the same time to per- Init, ready disengagement for renewal orcleansing, and that by the provision of a lurality of channels 2 l guard against liability of an inoperative device through choking in Patented Jan. 22, 1907.

' nected with the body portion and in open I claim as new, and desire to secure by Letbody portion, said tube projecting among the bristles and portion, a dentrifice-chamber removablycon one channei? The brush-back and supplytube may be readily'disconnected from the I body 1 when desiredfor cleansing or renewal. l,

The structure described comprises a simple fountain tooth-brush readily adapted for convenient operation and thoroughly eflicient in use. I

Having now described my invention, what ters Patent; is

2. A tooth-brush comprising ahollow body nected with said body portion and incommunication therewith, a valve normally closing said communication, means for operating said valve, a bristle-back connected with the body portion, and a tube removably concommunication therewith, said tube projectmg among the bristles of the back and arranged channels, a

formed with openings to permit the material passing through the tube to reach the bris;
